    Returns a SchemaBuilder for a decimal number depending on JdbcValueConverters.DecimalMode. You can use the resulting schema builder to set additional schema settings such as required/optional, default value, and documentation.
    
    Parameters:
    
    mode - the mode in which the number should be encoded
    
    precision - the precision of the decimal
    
    scale - scale of the decimal
